LM201AN - Single Non-Compensated Op Amp | STMicroelectronics
MPN: LM201AN ✓ Hoạt độngLM201AN Tóm tắt
An operational amplifier is a high-gain, differential-input analog building block used to amplify voltage differences, buffer signals, and perform linear operations such as summation, integration, and filtering. The LM201 belongs to the broader hierarchy of operational amplifier, analog amplifier, analog IC, and semiconductor. Unlike a unity-gain-stable amplifier with internal compensation, the LM201AN is externally compensatable, allowing the circuit designer to select a compensation capacitor suited to the gain, bandwidth, and stability requirements of a particular application.
Key features include a low input offset current, a maximum of 20 nA over temperature, and user-selectable compensation. These characteristics are especially relevant to precision analog circuits in which bias-current loading, input balance, and closed-loop stability can materially affect signal integrity. The device is offered as a single amplifier rather than a multi-amplifier package, simplifying board partitioning when separate analog channels require independent compensation or grounding.
The non-compensated architecture gives designers control over stability-bandwidth tradeoffs. A compensation capacitor can be omitted or changed for unity-gain service, while larger values or added frequency compensation can improve stability in noise-gain configurations. With proper compensation, the manufacturer-reported capability includes a slew rate of up to 10 V/µs. This makes the LM201AN potentially useful where signal speed matters more than the compactness of a fixed-compensation amplifier.
Typical applications include precision instrumentation amplifiers, logarithmic and summing amplifiers, active filters, transducers with relatively high source impedance, laboratory measurement systems, and low-frequency analog signal-conditioning chains. Its external compensation also permits optimization for different closed-loop gains rather than imposing one fixed stability profile across every application.
When designing around the LM201AN, select the compensation network for the actual noise gain and verify closed-loop phase margin on the assembled board. Keep input and output return paths short, observe the device's specified supply and common-mode limits, and prototype compensation before high-volume production. External compensation makes the part flexible, but it also places a stability responsibility on the engineer.
This page combines confirmed manufacturer-distributor data with clearly marked gaps, practical compensation guidance, package-aware replacement analysis, and procurement information. It distinguishes verified LM201AN characteristics from unverified specifications so engineers can make faster component-selection decisions without mistaking generic amplifier assumptions for device-specific facts.

Ứng dụng tiêu biểu
LM201AN phù hợp cho 6 Áp dụngs: Precision Instrumentation Signal Conditioning, Externally Compensated Summing Amplifier, Active Filter and Equalization Circuit, Laboratory Measurement Front End, High-Impedance Transducer Interface, Low-Frequency Analog Control Loop.
Precision Instrumentation Signal Conditioning
The LM201AN fits precision instrumentation signal-conditioning stages where low input bias is important and the closed-loop gain is known in advance. Its maximum input offset current of 20 nA over temperature helps limit bias-related error when working with moderate-impedance sensors, while the non-compensated architecture permits component selection for the required noise gain. According to the on Semiconductor datasheet description, proper compensation supports operation with a slew rate as high as 10 V/µs. In practice, the amplifier should sit close to the protected sensor connection, use short feedback paths, and include an external compensation network selected from stability analysis rather than copied without checking the source impedance.
Được đề xuất
Externally Compensated Summing Amplifier
The LM201AN is well suited to a summing-amplifier implementation because its compensation capacitor can be selected after the resistor network and required closed-loop gain are established. According to the available manufacturer description, the device permits optimized compensation and can achieve a slew rate of up to 10 V/µs when properly compensated. This flexibility is valuable for combining several analog signals or scaling an input through an inverting summing node. The design should account for the effective noise gain of every input branch, preserve resistor matching when offset cancellation matters, and verify stability with the actual source impedances and output load connected.
Được đề xuất
Active Filter and Equalization Circuit
The LM201AN can support active filtering and equalization circuits in which compensation is chosen to balance bandwidth, gain, and phase margin. Its one-circuit 8-pin PDIP format allows each filter section to use an independent compensation value, while the confirmed 20 nA maximum input offset current helps constrain bias-current error in moderate-impedance networks. According to the manufacturer description, suitable compensation can produce a slew rate of up to 10 V/µs. For dependable results, calculate the closed-loop response with the full resistor network, test tolerance and temperature effects, and avoid treating the LM201AN as a fixed-compensation unity-gain amplifier without analysis.

Laboratory Measurement Front End
The LM201AN is applicable to laboratory and instrumentation front ends that need externally adjustable compensation rather than a fixed internal profile. The 8-pin PDIP package is convenient for prototyping, and the device's 20 nA maximum input offset current is a relevant parameter when evaluating bias effects at the input. According to the available on Semiconductor description, proper compensation can yield a slew rate as high as 10 V/µs for signal-conditioning paths. Engineers should determine the required noise gain, select a compensation capacitor that provides adequate phase margin, place the input network close to the package, and validate operation across input amplitude and frequency before using it as a measurement amplifier.

High-Impedance Transducer Interface
The LM201AN can interface transducers whose source impedance makes input-bias current an important design consideration. The confirmed maximum input offset current of 20 nA over temperature provides a basis for evaluating the input-bias contribution in high-impedance circuits, while external compensation lets the designer optimize the stage for its particular gain and bandwidth. According to the manufacturer description, suitable compensation supports slew rates as high as 10 V/µs. Practical implementation should include input guarding to reduce leakage, a defined return path for bias current, short sensitive traces, and a protection network that does not add excessive capacitance or leak current.
Được đề xuất
Low-Frequency Analog Control Loop
The LM201AN is suitable for low-frequency analog control loops in which the designer wants direct control over compensation rather than a fixed internal compensation network. Its single-amplifier 8-pin PDIP format supports straightforward insertion into an error-amplifier or drive stage, and the documented 10 V/µs achievable slew rate provides a useful dynamic-performance target when properly compensated. According to the available LM201AN documentation description, the compensation capacitor is selected to suit the application. Engineers should model loop gain and phase across the full intended bandwidth, include component tolerances, keep feedback routing compact, and verify startup and saturation behavior in the complete control circuit.

Ghi chú thiết kế
Do not treat the LM201AN as a fixed-compensation, unity-gain-stable amplifier. According to the manufacturer description, the user selects an external compensation capacitor suited to the intended circuit. Determine the effective noise gain, including the noise-gain frequency behavior, and choose compensation that provides adequate phase margin. A previously working LM301 circuit may not transfer directly because its compensation architecture and stability profile may differ.
Keep the external compensation capacitor, feedback components, input resistors, and output path close to the 8-pin PDIP footprint. Route sensitive input signals away from the compensation node and output trace where possible, and provide a quiet ground return. Because bias-current errors increase with source impedance, use guarding or a defined reference return for high-impedance sources. Verify the assembled layout with transient or phase-margin testing because breadboard capacitance can materially change compensation.
Calculate the LM201AN operating conditions against the exact manufacturer document before finalizing the power design. The supplied snippets confirm a 20 nA maximum input offset current over temperature and a 10 V/µs achievable slew rate, but they do not provide verified supply-voltage, output-swing, or absolute-maximum ratings. Do not infer those limits from another LM201 manufacturer. Check input common-mode range, output headroom, supply tolerance, and power dissipation using the datasheet belonging to the exact supplier.
Validate the closed-loop response with the intended source and load impedances rather than relying on an open-loop gain plot. The confirmed 10 V/µs maximum slew-rate capability applies only when compensation is proper, while large-signal behavior also depends on output swing and supply voltage. Use a conservative target below the verified limit, check settling time at the required resolution, and include parasitic PCB and socket capacitance in the compensation calculation.
